" DIRIGIBLE .irnantrei'rrl Application filed Janiiary 2a, 1919,

To all whom it may concern: I

Be 1t known that we, HARRY EQCARY and THOMAS T. MCGUIRE, citizens-of the United 1 States, residing at Oakland, in the county ofAlameda and State of California, have invented certain new and useful Improvements in Dirigible Headlights, ofwhich the following is a specification. J

This invention relates to illumination, and more especially to dirigible light supports which are automatic; and'the object of the same is to produce a structure of this type wherein one lamp will-be turned aside when the course of the machine is altered and the other will remain stationary.

Another object is to adapt the attachment to machines fasten the operating mechanism to'the connecting rods at either side.

I Another object is to provide means for holding one lamp quite steady while the other is turned.

Yet other objects will appear in the following specification and claim and attention isinvited to the drawings wherein Figure 1 isa front elevation of this attachment complete.

Figure 2 is a horizontal sectional view of the device, taken on the line 2-2 of Figp I *the rock shaft 4, and by this means both shafts are. drawn ure 1. 7

Figure 4 is an enlarged plan view with the caps of the gear housings removed.

a vertical section on the line o'f'the'shaft.

Figure 5 is 5-5 of Fig. 4. V

Figure '6 is a side elevation of one gear housing with its capin section, and

Figure 7 is a vertical section on the line 77 of Fig. 6.

In the drawings, the letter F designates the frame of the automobile and R the rod which connects the two steering knuckles.

These knuckles sometimes project to the rear and sometimes to the front and therefore the rods B may move one way orthe other when the wheels are turned to the right, but my attachment makes provision for this difference in structure. The letters L designate the lamps mounted in standards S as usual. No novelty is claimed for the parts thus'far described.

Attached to each frame bar is a bracket 1 which supports an upright gear housing 2 and a removable cover or cap 3 to enclose the gears yet to be described. J ournaled in Specification ofiLetters Patent.

p the housing is a shaft 4 which 'depends'to I a pomt below the frame F, and connected V at 5'to theshaft is an arm 6 "herein shown as leading forward.

rigidlvconnected at the-point '9 as by means r of a clip'b'est seen in Figure 3. "It follows =that'when the connecting rod is moved the arm 8 moves with-itand the link 7 causes the arm 6to swing so thatthe shaft 4 is oscillated in its'bearing within the housing. If the connecting rod is in rearof the front axle, the oscillation will be in'one direction,

whereas if the connecting rod is in front of the front axle the oscillation will be in the other direction, so that its arm In that case, thelength of the arm 6 and the arm 8 will be changed, *butgthe link '7 and its ball-and-socket joint will yet be employed.

The lamp standards is -rota-tably mounted part of the housing 2, and

in the forward carries at its lower end a nut 10 above WlllCll is-a sprlng washer 11. A similar nut 12 and spring washer 13 are'mounted on downward within the and the expansion of the spring uptsome' little friction or resistance against the rotation Fast on .the upper end of the shaft 4 is a gear 14 meshing with teeth 15 housing,

rack along-the rear edge of a bar 16 which extends across the machine to "the opposite 1amp,-and this bar bypref- 'erance hasa turnbuckle .17 within its length" -or other IlGfins for adjusting it {when desired. Guide blocks 1 8 are"formed within 1 the housing and between these the bar reciprocates as the power gear 14 moves it in one direction or the other. In Figure '4, what would be the right hand gear is connected with the rod R and moved thereby, and therefore, the other gear apparently is simply an idler. But it will be clear that if the arm 6 were attached to the lower end of the shaft 4 of what would then be the left hand gear, as is desirable with some makes of machines, then the right hand gear would become an idler. Accordingly, we prefer to have gears at both sides or in both 7 .set if ing rod R, the arm housings, so that the connecting of the link -while its teeth engageteeth 25 on the bar at the end thereof. A guide block 28 is also provided for engagement by the smooth portion of the front edge of the bar, but it my front of the bar and at the outside of the housing.

'Tl 'ith the preferred construction, the parts having been properly applied, the action is as follows: As soon as theoperator turns the steering wheel and moves the connect- 8 moves with it and the link 7 causes a corresponding and simultaneous movement of the arm 6. This turns the power gear in one direction or the other and reciprocates the bar -16 and turns the other gear. The smooth portion of the front edge of the bar slides along the chord 23 in both mutilated gears until the teeth 25 at the outer end of the bar which is being drawn inward engage the teeth of one of these mutilated gears. The latter is now turned, and accordingly the lamp standard S at that side of the machine is turned and the lamp L is caused to direct its rays to one side. Meanwhile the smooth portion of the bar 16 at the other side of the machine slides over the chord 28, and the mutilated gear there is not turned. Therefore, the lamp at that side of the machine continues to direct its rays'straight ahead. The'result is that the driver has one lamp directly ahead and the other throwing its rays in the direc-a tion in which he is about to turn. Having turned and straightened out on his course, the'parts are restored to their original position. Adjustment of the length of the bar 16 by means of the turn buckle 17 or other device employed, will cause the inner ends of the front tooth racks to approach or recede, from the mutilated gears, and therefore result in the action of these mutilated gears earlier or later as is desired. It has been suggested above how the parts might be preferred so thatthe arm6 projects to,

be wise to omit the guide block in a for connection with B through the link the rear of the shaft the connecting bar mechanism described. Also, that by removing the pin 5 the arm 6 can be attached to the lower end of the other shaft 4: from that illustrated in the drawings. Therefore, the purchaser has considerable latitude in the application of this device or attachment, and can readily apply it to his machine. a. 1

The foregoing description and the drawings have reference sidered the preferred, or approved form of our invention. It is to be understood that we may make and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is In combination with a frame, brackets it will be clear to what may be consuch changes in construetion and gear housing carried thereby secured to the frame, a steering apparatus, a rotatable shaft in each of the. gear housings operable by the steering apparatus,:a rotatable lamp standard within each of said housings, a toothed gear and mutilated gear secured on the upper ends of the respective shafts and standards of each housing, a transversely extending rack bar operable therewith and in mesh with said gears, each of said mutilated gears having a flattened side adapted to normally maintain the same outof, engagement with the rack bars,

whereby the mutilated gears will be causedto rotate as the said rack bar is moved in one direction for independently rotating the lamp standards upon opposite sides of the frame at selected time, and means co-operat-. ing with said steering apparatus and said rack bar for automatically shifting the same as said steering apparatus is operated.

In testimony whereof we afiix our signatures in presenceof two witnesses.
